濕式電除塵器是一種用來處理含微量粉塵和微顆粒的新除塵設備，主要用來除去含濕氣體中的塵、酸霧、水滴、氣溶膠、臭味、PM2.5等有害物質，是治理大氣粉塵污染的理想設備。

濕式電除塵器通常簡稱WESP，與干式電除塵器的除塵基本原理相同，要經歷荷電、收集和清灰三個階段。

濕式電(dian)除塵器主要(yao)有(you)兩(liang)種結構形(xing)式，一種是(shi)使(shi)用(yong)耐腐(fu)蝕(shi)導(dao)電(dian)材料(liao)(liao)（可以(yi)為導(dao)電(dian)性能優良的(de)(de)的(de)(de)非金(jin)(jin)屬材料(liao)(liao)或(huo)(huo)具有(you)耐腐(fu)蝕(shi)特性的(de)(de)金(jin)(jin)屬材料(liao)(liao)）做集(ji)塵極，另一種是(shi)用(yong)通(tong)過噴水或(huo)(huo)溢流水形(xing)成導(dao)電(dian)水膜，利(li)用(yong)不(bu)導(dao)電(dian)的(de)(de)非金(jin)(jin)屬材料(liao)(liao)做集(ji)塵極。
